6 Claims. (Cl. 23S-146) This invention relates to a computing machine, and more particularly to a change listing attachment for an adding machine.

The object of the invention is to provide a change listing attachment for an adding machine which will simplify the obtaining of change for payment of pay rolls or the like.

Another object of the invention is to provide an attachment which is adapted to be detachably mounted on a conventional adding machine such as that shown in prior Patent No. 2,745,601 or 2,665,063, so that by means of such attachment a person can readily compute the exact amount of change required for a given purpose, as for example, for use in making up a pay roll.

A still further object of the invention is to provide a change listing attachment for an adding machine which is electrically operated, the attachment of the present inf vention including a base which carries a plurality of manually operable switches that are adapted to actuate solenoids whereby actuation of the solenoids will depress arms which will move certain of the keys on the adding machine.

A further object of the invention is to provide a change listing attachment for an adding machine which is ex- `tremely simple and inexpensive to manufacture.

Other objects and advantages will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are used to designate like parts throughout the same.

-A Figure 5 is a disassembled view illustrating certain constructional details of the assembly.

Figure 6 is a fragmentary perspective view illustrating the channel members and movable arms.

Figure 7 is a view similar to Figure 6 but showing a modification.

Figure 8 is a view illustrating the wiring diagram of the present invention.

Referring in detail to the drawings, the numeral 10 designates a conventional adding machine which includes the usual housing or casing 11. The adding machine 10 -is provided with the usual roll of paper 12 on which is adapted to be printed the various numerals or indicia.

The present invention is directed to.a change listing attachment for use with the adding machine 10, and the change listing attachment of thepresent invention includes a `body member 13 which can be made of any The body member 13 includes an in- A United States Patent ICC downwardly extending lip 15, and the lip 15 terminates in a substantially horizontal flange 16 which is adapted to be arranged in engagement with brackets 17 which are secured to the housing of the adding machine 10.

Depending from the lower edge of the base 14 is a verticalportion 18 which has a horizontal portion or plat'- form 19 extending therefrom, and the platform 19 provides a support for a plurality of solenoids 20. The solenoids 20 are adapted to actuate movable arms 21. Each of the arms 21 may include a vertical section or portion 22 which has a shoulder 23 on its lower end for coaction with the core 24 of the solenoids 20. Vertical portions 25 depend from the horizontal portions 19, and the vertical portions 25 of the body member 13 are adapted to engage brackets 26 on the adding machine 10 so as to retain the parts in their proper assembled position.

For supporting the movable arms 21, there is provided a pair of channel members which are each indicated by the numeral 27, Figure 6. The channel members 27 may have an L-shape in cross section, and the channel members 27 are provided with apertures or openings 28 for slidably receiving the vertical portions 22 of the arms 21. Brackets 29 are provided for releasably connecting the channel members 27 to the adding machine 10. Coil springs 30 are circumposed on .the vertical portions of the arms 21, and the coil springs 30 may be interposed between the pair of channel members 27.

The arms 21 further include upper portions 31 which are each provided with a head 32 on the end thereof. The heads 32 are mounted for movement into and out of engagement with certain of the depressable keys 33 of the adding machine 10. A plurality of manually operable switches 34 are carried by the base 14, and the switches 34 are arranged in an electrical circuit as shown in Figure 8. A portion of the base 14 is cut away as at 35 for a purpose to be later described, Figures l and 4.

Referring to Figure 7 of the drawings, there is shown a modification which is adapted to be used in lieu of the arrangement shown in Figure 6. Thus, in Figure 7`the numeral 36 designates an L-shaped channel member which is provided with struck out portions 37 that have apertures or openings 38 therein for slidably receiving the arms 31.

The numerals 39, 40, 41 and 42 designate the keys of the adding machine which are exposed through the cutout portion 35 of the base 14.

From the foregoing, it is apparent that there has been i provided a change listing attachment for a computing machine such as an adding machine. The four keys 39, 40, 41 and 42 are left uncovered or exposed due to the cut away portion 35, and these keys 39, 40, 41 and 42 are manually operated. The arms 21 serve to depress the keys 33. As shown in the drawings, the base 14 is arranged above the keys 13. The adding machine 10 is electrically operated. The switches 34 serve to actuate the solenoids 20, and the solenoids 20 pull the shoulders 23 of the arms 21 towards the solenoids so that the heads 32 will depress the keys 33 therebelow. After the solenoids 20 have been deenergized, the coil spring 30 returns the arms 21 to the position shown in Figure 2. Figure 8 illustrates the circuits or electrical connections between the switches and solenoids. Thus, as shown in Figure 8 for example there are four connections or circuits so that for example when the change for ninety cents is required, the following keys will be depressed so as to make a mark lon the paper roll 12. Five cents, ten cents, twentyve -cents and fifty cents so that the total will be ninety cents.

Similarly, when the change for thirty cents is required, it will be seen from Figure 8 that a circuit to the twentyve cent solenoid and to the live cent solenoid will ,be actuated.

y live dollars to titty-live dollars.

In Figure 7 there is illustrated a modification wherein the numeral 36 designates a movable base which is provided with the four slots 43 which permit the base to be moved sideways and when the base 36 moves sideways, the arms 31 likewise move sideways so that when operating the machine in order to find out the change for the bills, the base 36 will be moved towards the right. -For purposes of illustration, the six arms or depressors 31 are indicated by the numbers 1, 2, 3., 4, and 6. Thus, when operating the machine in order to nd out the change for bills, the base 36 can be moved towards the right so that the depressor or arm marked 2 will be above the key 1 of column 4 of the keyboard of the adding machine. This will permit three columns of the adding machine for recording the one dollar bills; two columns for the tive dollar bills; two columns for the ten dollar bills and three columns for the twenty dollar bills. This arrangement will only be used when listing the change for the bills. When listing the change for the coins, the base 36 holding the six depressors 31 will again be moved to the left so that the depressor marked 2 will be above the key l of column 5 of the key board.

Due to the provision of the brackets such as the brackets 26, 29 and 17, the device can be readily attached to or removed from the adding machine when desired.

It is to be understood that the present invention is directed to an attachment for use with a conventional adding machine such as the adding machine 1t). The present invention is electrically operated and consists of a minimum number of parts. Also, the present invention utilizes the existing printing mechanism including the roller 12 and keys 33 of the adding machine to which the `device is attached. With the present invention, different denominations for coins and bills are printed on the paper roll normally used by the adding machines. Furthermore, the present invention can be used with either adding machines which are electrically operated or hand operated. Also, the present invention gives the exact amount of all denominations.

The device or mechanism of the present invention is adapted to be used for determining the change needed for the payment of pay rolls and the attachment includes six electro magnets or solenoids 20 which are connected to the different switches 34 on the panel or base 14 that is arranged on top of the machine keyboard. The electro magnets 20 operate the six arms 21 which in turn serve to depress the keys 33 according to the different connections made to each switch.

The switch panel on top of the keyboard consists of thirty switches 34. Eleven of these switches are for bills while nineteen of the switches are for coins. The switches for the bills will be in a progression of tive from The coins will also be in a progression of tive, from tive cents to ninety-five cents. The pennies will be operated manually, for which purpose the iirst four keys 39 through 42 of the right hand column are not covered by the panel. For example, if it is necessary to figure out twenty-nine cents, then the operator merely depresses the switch marked twentytive and the uncovered key forty-two which has the numeral 4 thereon.

When using a ten column adding machine, the keys will be divided into live groups. The irst two keys from left to right are for the halves, the next keys for quarters, the next two keys for dimes, the next two keys for nickels, and the last two keys for pennies.

The arms or key operating depressors 21 are operated by the electromagnets 20 and are distributed from right to left as follows. For the coins, arm 1 will depress key 1 of column 3 for the nickels. Similarly, arm 2 will depress key l of column 5 for the ten cents. Also, arm 3 will depress key 2 of column 5 for the twenty cents. Furthermore, the arm 4 will depress key 1 of column 7 for the quarters. The arm 5 will depress key 1 of column 9 for the halves.

For the bills, arm 2 will depress key 1 of column 4 for the five dollar bills. of column 6 for the ten dollar bills. Further, arm 5 will depress key 1 of column 8 for the twenty dollar bills. Similarly, arm 6 will depress key 2 of column 8 for the quantities of forty dollars.

As previously described, the pennies will be operated manually and for this purpose the keys 39 through 42 of the first column from the right will be used.

The thirty switches of the panel will be of one, two, three and four contacts as follows:

One contact switches-for the coins: 5, 10, 20, 25, 50; for the dollars: $5, $10, $20 and $40.

Two contact switches-for the coins: 15, 30, 35, 45, 55, 60, 70 and 75; for the dollars: $15, $25, $30, $45 and $50.

Three contact switches-for the coins: 40, 65, 80, 85, for the dollars: $35 and $55.

Four contact switches for the coins 90.

As shown in the drawings, the change listing attachment of the present invention is mounted on top of the keyboard of the adding machine and the device is held in place by suitable fasteners such as the previously described bracket. However, other types of fastening means can be used if desired.

As an example of how the attachment is used, assuming for example that it is desired to determine the change needed for the following amounts in a pay roll, $29.40, $18.20 and $6.44. Then, it is only necessary to proceed as follows: First, the operator determines the bills required by depressing the following switches, $25 and the uncovered key No. 42 which has the numeral 4 thereon, the key 42 being part of the adding machine; the switch marked $15 and the uncovered key with the numeral 3 thereon which is indicated by the numeral 41 on the adding machine; the switch marked $5 and the uncovered key indicated by the numeral 39 and having the number 1 thereon. Then, to determine the change for the coins, it is only necessary to depress the switch 34 marked 40, then the switch 34 marked 20, then the switch marked 40 and the uncovered key with the numeral 4 thereon, the last named key being a part of the adding machine.

The attachment of the present invention can be used on a hand operated machine or on an electric operated adding machine as desired.

The following is given as a detailed description of the operation of the change listing attachment.

Referring to Figure 2 of the drawings, the body member 13 is placed on top of the keyboard of a conventional adding machine which may be electrically or manually operated and which has at least ten columns of keys. The body member 13 is held in place by suitable fasteners so as to permit easy attachment and removal thereof. When placing the body member 13 on top of the adding machine, the head 32 of the depressors will be at least 1A of an inch above the keys 33 and the head 32 of the iirst depressor (counting from right to left) will be above the first key 33 of the column 2 of the keyboard. The head 32 of the second depressor 31 will be above the :first key 33 of the column 4 of the keyboard. The head 32 of the third depressor 31 will be above the second key 33 of column 4 of the keyboard. The head 32 of the fourth depressor 31 will be above the rst key 33 of the column 6 of the keyboard. The head 32 of the fth depressor 31 will be above the first key 33 of column 8 of the keyboard and iinally, the head 32 of the sixth depressor 31 will be above the second key 33 of column 8 of the keyboard.

As shown in Figure 7, the six depressors 31 are mounted on a movable base 36 so as to permit the base to move either to the right or to the left. Bymoving the base 36 to the right so that the previously described six depressors 31 are in the position explained above,

Also, arm 4 will depress key 1 the change listing attachment is ready to operate so as to determine first the denomination of the bills required. This is done by depressing the switches 34 which are carried by the base 14. There are eleven switches 34 which will permit the operator of the machine to determine the change required for the bills in the denominations of $5.00, $10.00 and $20.00.

' The $1.00 required is determined by manually depressing the first four keys 33 of column 1 of the keyboard, which for this purpose has been left uncovered `by the base or body member 13. As an example, assume that it is desired to determine the change in bills for the following amounts in a pay roll: $5.00, $10.00, $20.00, $15.00, $25.00, $50.00, $55.00, $65.00, and $75.00; then it is only necessary to proceed as follows. Depress switches 34 which are marked $5.00, $10.00,

V$20.00, $15.00, $25.00, $50.00, $55.00, and then switches $55.00 and $10.00 (for the $65.00) and the switches $55.00 and $20.00 for the $75.00. It is to be noted that after depressing each switch, it is necessary to press the operating bar of the machine so that each amount will be individually registered and printed on the paper roll of the adding machine. If the amounts in the payroll are $6.00, $16.00 and $24.00, it is only necessary to depress switch 34 which is marked $5.00 and the un'- covered key 39 of the first column; the switch 34 marked $15.00 and the uncovered key 39 of the first column; and switch 34 marked $20.00 and the uncovered key 42 of the first column.

After the change for the bills of the payroll is deter- A.mined as explained above, the following procedure is Icarried out in order to determine the change for the coins. As aV general rule ofiice personnel determines the change required for the first sheet of the payroll, next the change for the second sheet and then the change for the third sheet, etc. First, the movable base 36 is shifted to the left so that the head 32 of the first depressor 31 is above the first key 33 of the column 3 of the keyboard and the other depressors are in the position as shown in VFigure 3 of the drawings. The switches 34 are now ready to operate which are carried by the base 14 and there are. nineteen of these switches which are used in order to determine the change for the coins in the denominations five cents; ten cents;- quarters; and half dollars.

The switches are marked with numbers 5, l0, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65,70, 75, 80, 85, 90, and 95. These switches have been arranged in two columns but it is to be understood that they can be arranged in three columns or in any other desired arrangement.

As an example, let it be assumed that the following amounts appear on a pay roll; 5 cents, 10 cents, 15 cents, and 20 cents. Then, it is only necessary to proceed as follows: Depress the switches 34 marked with the above denominations 5 cents, 10 cents, 15 cents and 20 cents. After depressing each switch individually, the operating bar of the adding machine will be depressed so as to register and print the amounts on the paper roll of the adding machine. If the amounts are 6 cents, ll cents, 14 cents, it is only necessary to depress the switch 34 which is marked 5 cents and the uncovered key 33 marked 39; the switch 34 marked 10 cents and the uncovered key 33 marked 39; the switch 34 marked 10 cents and the uncovered key 33 marked 42.

By way of further explanation of the circuits shown in Figure 8 the following is given, The switch marked 5 is a one Contact switch and when it is depressed it closes the circuit between the line and the solenoid number one (counting from right to left). This closing of the circuit energizes the solenoid 20 and this causes the solenoid to pull the shoulder 23 of the arm 21 towards the solenoid and then the head 32 pushes the key 33 downward. As soon as the pressure of the finger of the switch 34 is removed a spring in the switch will break the circuit and the solenoid 20 will be deenergized. This will permit the coil spring 30 to return the arm 21 to its original position shown in Figure 2 of the drawings. At this moment, the operator of the adding machine presses down the operating bar of the machine and the operation is recorded on the paper roll of the adding machine. The key 33 of the adding machine in this case will be the first key of column 3. If the switch marked 10 is depressed, the solenoid actuated would be number 2 (from right to left) and key 1 of column 5 will be depressed. If the switch marked 15 is depressed, it will closethe circuits for the 5 and 10 and the sol-enoids affected will be l and 2. Key l of columns 3 and 5 will be depressed. Since the other switches will operate as previously described, it is not believed necessary to repeat the function of each one. However, there is submitted herewith immediately following this material, information which explains in detail the number of contacts in each switch, the circuit it closes, the solenoid actuated, and the keys of the adding machine which will be depressed.

Below is a description of the eleven switches of the change listing attachment which are used in order to obtain the change required for the bills in the payroll.
